Quoted from Rdoyle1978:LEDOCD and GIOCD are incredible but can be subtle - you kind of have to try it in person. IMO they are critical on TZ but you'd have to try it in your game to tell for sure.
Also those products do not do anything for flashers. Not sure if you knew that
Personal choice on replacing flashers with LEDs; many people find them too bright and keep incandescent on purpose. There are lots if options though; check comet for the lower brightness flashers
Replacing bulbs the first time can be a little overwhelming, thrrr are SO many choices / Do you color match, use coloured bulbs for GI, etc, how bright is too bright?
Using a prepackaged set is fine but it is WAY more expensive than buying your own, but it takes a lot of guesswork out of the first time. I'd say Do it the first time and get comfortable then buy in bulk next time
I just want to make sure I clear up this miscon option again. Our kits are the exact products included and usually rounded down 5-10$. We don't do any markup on the ultimate kits like other vendors may do.
